Analysis of risk factors associated with hepatocellular carcinoma in black South Africans: 2000-2012.

OBJECTIVE: The aims of this study were to determine the prevalence of risk factors associated with hepatocellular carcinoma (HCC) in black adult South Africans and to estimate the size of the associated risks. METHODS: A case-control analysis of 150 black South African patients (aged 18-75 years) with HCC-who were a subset of patients recruited for the Johannesburg Cancer Case Control Study 2000 to 2012-was undertaken. The association between this tumour and hepatitis B/C virus infections, and human immunodeficiency virus (HIV) mono- and co-infections was investigated. Odds ratios (ORs) and 95% confidence intervals (CI) adjusted for age, year of diagnosis, marital status, place of birth and selected modifiable risk factors were calculated. RESULTS: HCC was significantly associated with a rural birthplace (p2000 IU/ml (OR 8.55; CI:3.00-24.54) to ≥200,000 (OR 16.93; CI:8.65-33.13), anti-HCV (OR 8.98; CI:3.59-22.46), HBV DNA+/HIV+ co-infection (OR 5.36; CI:2.59-11.11), but not with HBV DNA-/HIV+ (OR 0.34; CI:0.14-0.85). We did not find a synergistic interaction between HBV and HIV. Modifiable risk factors (alcohol consumption, tobacco smoking, number of sexual partners, diabetes and hormonal contraceptive use) were nonsignificant. DISCUSSION: A considerable portion of the HCC burden in Johannesburg and surrounding provinces falls on rural migrants to urban areas, most of whom are men. The HBV will continue to contribute to HCC incidence in older age-groups and in others who missed vaccination. Although we did not find an increased risk for HCC in HIV positive individuals this may change as life expectancy increases due to greater access to antiretroviral therapies, necessitating the addition of hepatitis virus screening to preventive medical care

Initiation of HIV Reverse Transcription

Reverse transcription of retroviral genomes into double stranded DNA is a key event for viral replication. The very first stage of HIV reverse transcription, the initiation step, involves viral and cellular partners that are selectively packaged into the viral particle, leading to an RNA/protein complex with very specific structural and functional features, some of which being, in the case of HIV-1, linked to particular isolates. Recent understanding of the tight spatio-temporal regulation of reverse transcription and its importance for viral infectivity further points toward reverse transcription and potentially its initiation step as an important drug target

Digital Content Contracts for Consumers

The application of consumer law to digital content contracts encounters a number of obstacles. Some of these are rather typical for digital content markets, e.g., the legal consequences of the classification of digital content as “goods” or “services”, and more importantly, the absence of general benchmarks to evaluate the conformity of digital content. Other problems, such as the limited usefulness of consumer information and the position of underage consumers, are not as such reserved to digital consumers, but they are amplified in the digital content markets. Moreover, particular attention is paid to the complex relationship between copyright law and consumer law. This paper explores the extent to which consumer (contract) law is fit to address the problems faced by digital consumers wishing to enjoy the benefits of digital content and examines whether the on-going initiatives at national and European level are likely to provide relief. Finally, recommendations for improvement are put forward in cases where the analysis shows that the problems identified are not or are insufficiently solved by these initiatives

Giving voice: a public sphere theory of European private law adjudication

This Article addresses the question of how to explain and justify the allocation of politically sensitive legal questions to civil courts in the European Union. It proposes a pluralist theoretical view on interactions of private law adjudication with legislative initiatives in the process of building a European political community. This is elaborated on the basis of a reconstruction of the interaction between judicial and legislative processes in three high-profile cases (concerning non-discrimination, housing and climate change) in light of three theoretical perspectives: social justice, constitutionalism and public sphere theory. The first two perspectives shed light on the legal-political dimension of private legal questions in the European Union and manners in which to handle the plurality of sources and institutions in this field. They do, however, not fully clarify the distinction and relation between Habermasian discourses of justification and discourses of application of law in European Private Law adjudication. The Article suggests that public sphere theory, with a basis in Fraser’s work on transnationalisation, can complement the theoretical understanding of the role of judges in European Private Law. It is submitted that the interaction between national and European levels of adjudication helps maintain transnational deliberative spheres in which the legal-political stakes behind private law can be discussed. This opens up space for the inclusion of different voices in democratic deliberations on questions of social justice. Private law adjudication may thus be considered to contribute to the initiation of discourses of justification which serve the re-imagination of a European political community
